UNIVERSAL JOINT FOR SHAFTS OF! SECTIONS OF SHAFTS.

Specification of Letters Patent. Patented April.- 9, 1907'.

Application filed May 2, 1906. Serial No. 314,744.

To all, whom, it may concern: lenticular end of the shaft b on the'bea between the-cylinders, whilethe horizoii t fi change of position ofthe shaft is obtained bythe movement of the cylinders upon the walls of the box. In the form shovm at Fig. 4 the top r is a removable cap having the threads n, Cylvhich mesh into threads 0 on the walls an H. GAULT, a c1t1zen of the .United States, residing at Phil- -Pennsylvania, have invented a new and useful Improvement in Universal Joints for lowing is a full, clear, and exact description, reference being had to the accompanying cap and the cap tis formed of frusto-conical drawings,'which form a part of this speoifishape, the upper and lower ends of the semication. cylinders being also frusto-con-ical.

My invention has for its object the producconstruction if there is any wear of the tion o .a universal joint for shafts or sections ders it can be takenup by the caps. of shafts which is of simple construction, I Having now fully described my-inventio'n, avoidin the use of pins and nuts and in I whatIclaim, and desire to protect byLetters which the wear is reduced to a minimum by l Patent, ispresenting a great area of bearing-surface, I 1. An universal joint forshafts, comprisand the friction of the wearing parts is reing a box connected to one shaft or section of duced to a minimum.

I will first describe the embodiment of my invention illustrated in the accompanying drawings and then point-out the invention in the claims.

Figure 1 is a front view of my invention partly broken away. Fig. 2 is atop view of section. Fig. 3 is a partial Fig. 4 is a partial section, similar to Fig. v3, with two caps. aand b are the two shafts or sectionsof a shaft to be connected together by the universal joint. To the end of the shaft a is connected the open-ended box having 'the-top c and e, a portion of the walls d and e being cut away to form an opening 7' for the movement of the "shaft 6. The walls e each have a curved extension upon are the threads f, with which mesh threads on the bottom. cap. g. Within this box are the two semicylinders hand i, which extend from t'opvto bottom of the box. Be-

cylinbox, to rotate horizontally therein, and a projection fro'mthe other shaft between said semicylinders, and having a bearing he-' (tlally with, and vertically between, said cyliners.

' 2. An universal joint for ing a box connected to one shaft o r.secti'on of a shaft, two semicylinders mounted in said box, to rotate horizontally therein, and a 'lenticular rojection from the other shaftbetween said semicylinders, and having a bearing between said cylinders, and movable horizontally with. and vertically between-,- said cylinders. 3. An universal joint for shafts, comprising a box connected to one shaftforsection of a shaft, two 'semicylinders mounted 'in'said box, to rotate therein, and a projection from the other shaft or section, having a bearin between said semicylinderss aid semicylinders and box being cut away tion from, and said shaft to move semicylindersa'nd its bearing.

.4.An universal joint for shafts," comprising a box connected to one shaft or section'o'f a shaft, two semicylinders mountedjin 'said' box, to rotate therein, a projection fromthe other shaft or. section having a bearingbemilled into them to receive it, is the lenticuwith said from the end of the b. The semicylinders have a cut-away portion '1 to allowfor oscillating movements at right angles toeaoh other of theshafts or sections' of shafts a and 5.. In practice the parts are associated together in the box in the followingmannerz The two semicylinders, with the shaft?) inserted be-' cap p is removed, the the e box, removably nticular end-of msertion of and box.
